Application Field and Preparation Method of MMA Methyl


Mma methyl is colorless crystal or transparent liquid with pungent odor. Soluble in hot water, soluble in most organic solvents such as ethanol and ether. Easily polymerized into water-soluble polymers. Combustible, there is a danger of burning in case of high heat and open flame, and it can produce toxic gas when heated.


1. Applications of MMA methyl


For organic synthesis and polymer preparation. It can be used as a raw material for synthetic rubber. Manufacture of thermosetting coatings, synthetic rubber, fabric treatments, etc. It is a monomer for the manufacture of acrylate solvent-based and emulsion-based adhesives to improve the adhesive strength and stability of the adhesive. Manufacture of coatings, insulating materials, adhesives and ion exchange resins. Used as an organic reagent, it is an important organic chemical raw material and an intermediate of polymers. Its important derivative, MMA methyl, produces plexiglass that can be used in aircraft and civil building windows, and can also be processed into buttons, solar filters and automotive lamp lenses; the coatings produced have superior suspension, rheology and durability properties. ; The prepared adhesive can be used for bonding metal, leather, plastic and building materials; Methacrylate polymer emulsion is used as fabric finishing agent and antistatic agent. In addition, MMA methyl can also be used as a raw material for synthetic rubber.

DOUWIN is a professional methyl methacrylate manufacturer in China, where you can get high quality methyl methacrylate.

2. Application areas of MMA methyl

(1) Coating industry


In the manufacture of coatings, MMA methyl produces coatings with superior suspension, rheology and durability properties.


(2) Synthetic rubber


Mma methyl is used in organic synthesis and polymer preparation. It can be used as a raw material for synthetic rubber.


(3) Adhesive industry


Mma methyl is a monomer for the manufacture of acrylate solvent-based and emulsion-based adhesives to improve the adhesive strength and stability of the adhesive.


Methyl methacrylate applications are very extensive.


3. Methods of making MMA methyl


(1) Acetone cyanohydrin method


In the presence of alkali catalyst, acetone and hydrocyanic acid react to generate acetone cyanohydrin, which is then reacted with concentrated sulfuric acid to generate methacrylamide sulfate, which can then be hydrolyzed to generate MMA methyl. In production, it is required that acetone cyanohydrin and sulfuric acid do not contain water, otherwise acetone or methyl hydroxyisobutyrate will be produced in the product, which will affect the quality of the product.


(2) Isobutylene oxidation method


Isobutylene is oxidized in two steps, the first step is to generate methacrolein, the second step is to generate MMA methyl, and then the qualified product is obtained by rectification. It can also be produced by replacing isobutene with tert-butanol.


(3) Methacrylonitrile hydrolysis method


Using isobutene as raw material, it is obtained by ammonia oxygen and hydrolysis.


(4) Isobutane oxidation method


Methacrolein is obtained by oxidation, and then obtained by oxidation.
